AUGUST LUDWIG EMIL BERGERT, OF JOHANNE'SBURG, TRANSVAAL'.

MEANS FOR DISTRIBUTING MINE RESIDUES.

To all whom it may concern.-

Be it known that I, AUGUsT LUDWIG EMIL BERGERT, a subject of the GermanEmperor, residing at Johannesburg, Transvaal, have invented certain newand useful Improvements in Means for Distributing Mine Residues and forother Similar Purposes, of which the following is a s ecification.

This invention as reference to apparatus intended more particularly fordistributing mine residuestl1at is to say, to apparatus intended forconveying to and dumping or depositing such residues upon amine-dump ordepositing site.

The invention is a plicable generally for conveying and distri utingover a limited area any kind of granular, pulverulent, or fragmentarysubstances or materials.

The apparatus comprises a wheeledframe or carriage which is ada ted totraverse a track or rails laid on the ump or depositing site, upon thetop of which frame or carriage is mounted a structure which pivotallysupports a boom or jib carrying an endless conveyer belt or band, ontothe receiving end of which is led the material to be conveyed anddistributed. The structure which is mounted on the carriage isconstructed to provide a curved track radial to the pivot or point aboutwhich the boom swings, upon which radial track a vehicle which supportsthe boom at or in proximity to the center of its length is free totravel as the boom is swung to either side of the main track or therails upon which the wheeled carriage runs.

The boom carrying the conveyer-belt is pivoted at its rear extremity insuch a way that it can swing in the plane of the carriage to either sideof the main track and so that it may oscillate about its longitudinalaxis to prevent the belt being inclined transversely when the boom isswung to either side of the main track.

My invention will be described in detail by aid of the accompanyingdrawings, inwhich- Figure 1 represents a side part sectional elevationof the apparatus located on a dump or depositing site. Fig. 2 representsthe apparatus in plan. Fi 3 is a front elevation of the vehicle whicserves for supporting the boom and conveyer-belt at or about the centerof their length drawn to an enlarged scale. Fig. 3 is a detail view ofthe vehicle and the curved track upon which it runs. Fig. 4 is a detailof the boom drawn to an-enlarged scale, Fig. 5 is a plan of the rearSpecification of Letters Patent.

end of the boom, showing the pivot about which it swings. Fig. 6 is asectional elevation on line a: y of Fig. 5. Fig. 7 is a sec-. tionalelevation of the rear end of the boom,,

illustrating a modification in the pivot about which it swings. Fig. 8is a detail view of the arran ement of the pivot supporting the boom.ig. 9 is a front elevation of the vehicle which supports the boom at orabout the center of its length and part of its radial track, showing theboom in its central position or arallel with the lines of the maintrack. ig. 10 is a view similar to Fig. 9, showing the conveyer-belt andboom in a osition at right angles to that in which t ey are shown inFig. 9 or at right angles to the main rails or tracks. Fig. 11 is anenlarged view of the forward end of the carriage, showing the means forsupporting the boom; and Fig. 12 is an enlarged view of a part of Fig.1, showing the chute T and the conveyer.

In Fi 1, A represents the rails which constitute t e main track laid onthe surface of the inclined dump or depositing site B, a being sleeperscarrying the rails A.

C is a square or rectangular frame mounted on the wheels c and adaptedto traverse along the rails or track A.- As illustrated, this frame C isshown comprising two arallel channel or U irons c at either side, w'chat their extremities carry the bearings c for the axles of the wheelsc and the two angle or -L irons c fixed between the U-ironsc at one endand the I or H iron 0 fixed between the U-irons c at the other end. Thisframe G is strengthened by means of the diagonal rods or bars 0 c.

On top of the frame or carriage G is fixed another structure comprisingtwo U-irons D, arranged transversely of the main track A, andasemicircular or approximately semicircular U-iron E, connected at itsextremities to the two channel-ironsD. Frepresents radial or aproximately radial I or H irons, which serve or strengthening andsupporting the curved channel-iron E by connecting it with the twotransverse channel-irons D.

G represents a jib or boom which serves for carrying the conveyer-beltJ, which effects the distribution of the residues or other material onthe surface of the dump B. This boom G consists of two parallel latticegirdare H H, consisting of the top and bottom angleirons h h and the anle-1ron braces h. The girders H H are staye by means of the plates orbars h. (See Fig. 2.) The rear end of the boom G is constructed so thatit may swing in either direction or to either side of the main track A.The pivot about which the boom swings is shown consisting of a block is,which forms the support for the pivot-pin k, secured between the twochannel-irons D at the center of their length and formed with lugs orprojections Ir, projecting over and under said channel-irons D. As seenin Fig. 6, the block K is formed with a hole k in which is revolublysupported the in /c. k is a washer, and k a split pin or the like on theend of the in Ir, below the block K, for retaining the pin in positiontherein. The boom G is capable of swinging in the plane of the dum Babout the pivot-pin k in block K.

Y Across t e top of the pin k is formed a slot 1c,

into which fits a plate or transverse piece In", pivoted or otherwisefixed between the lattice girders H H by means of the end flanges W.

L is a key or pin which passes through holes formed in the top of thepin it and passes through a coincident hole formed in that portion ofthe transverse plate k" which is located in the slot k (See Figs. 5 and6.) The boom G is free tooscillate about the pin k in a plane at rightangles to its longitudinal axis. The ends of the angle-irons h h arerigidly connected b means of transverse plates k riveted to t 1eangle-irons h h inside the girders H H, and by means of an end plate It,fixed to angle-p1eces or brackets k at the extremities of theangle-irons h h of the lattice girders H H.

In Fig. 7, illustrating a modified construction of the pivot for theboom G, 1) represents the two parallel channel-irons forming thecross-beam secured on the top of the carriage or frame C. At the centerof this cross beam D is fixed a plate It", formed with a conicalprojection is" and with a spherical head or ball k at the to The ball orsphere k fits into a spherica socket 7c", formed in halves and rivetedat the ends in flanges k" to the side plates 71" and angleirons h h ofthe boom G.

Secured on the top of the semicircular track or U-iron E is acorresponding semicircular rail e, and mounted u on and adapted totraverse this rail e is a ve 'cle'M. (Illustrated in detail in Fig. 3.)This vehicle is employed for supporting the boom G and conve er-belt Jat or about the center of their lengtl i. The vehicle facilitates themovement of the boom G about the pivot is when it is swung to eitherside of the main track A. The vehicle comprises a bottom frame,preferably of the shape shown, which consists of two end pieces m, acentral portion m arranged somewhat lowerthan the end pieces-m, and twoinclined parts mfieennecting the inner ends of the end pieces m with theends of the central parallel member m. These several .parts are wheelsN, on which the vehicle traverses the rail e. Bearings 2:, fixed on theend pieces m of the frame, are provided for the axles n of the wheels N.When the frame is made of two straight and parallel members, the axlesof the wheels are set radially to the pivot is about which the boom Gswings. To the ends of this frame and at either side are riveted orotherwise attached gusset-plates m", and to these gusset-plates m" areriveted or otherwise fixed the semicircular or arched girders we, alsoshown of U-section and connected underneath by means of the plates m andat the to by means of the curved plate m". To the Kent of the vehicle,outside the semicircular track E, is riveted a plate m formed with ahole m or provided with other means for attaching to it a wire or otherflexible hauling-rope O for the boom G. This wire ropeOis arranged torun round the semicircular track E, as shown in Fig. 2. To .the front ofthe semicircular U-iron E are fixed a number of vertically-disposedguide-rollers e, over which runs the wire rope .0.

On the carriage C, at the rear of the boom G, is located a winch rovidedwith a vertically-dis )osed drum F, (see Fig. 2,) round which thehauling-rope O is coiled. As shown in Fig. 2, the frame carrying thewinch consists of the two parallel I-irons 0 and the two transverse andparallel I-irons 0, secured thereto. It will now beunderstood that whenthe drum P of the winch is rotated the vehicle M is hauled round thesemicircular track E according to the direction of rotation of the drumP.

The boom G is pivotally suspended inside the semicircular or archedupper ortion m of the frame of the vehicle M. he means whereb this iseffected are illustrated more particuiarly in Figs. 3 and 4 of thedrawings. To the lattice girders II II on the inside are riveted plateswhich project above the top angle-iron h f dr some distance. To theseplates p are riveted two channel-irons p, which are inclined inward fromthe bottom to the top and are connected at the top by means of theplates p one at each side. The rivets fixing these plates p arecountersunk in the plates, so as to offer no obstruction to the movementor oscillation of the boom G in the arched frame. The upper ends of thetwo channel-irons p and their connectingplates 1) fit between the twochannel-irons m forming the arched frame, and the are pivotallyconnected in said archedframe y means of a pin 11 which passes throughholes formed in the two channel-irons m and through coincident holesformed in the plates p.

At or in proximity to the top of the channel-irons p by which the {boomG is sus ended in the arched frame and at each side t ereof are fixedtwo plates p, and at a suitable distance from the plate 1), attached tothe lattice girders H H, are fixed plates to which are riveted anle-irons p, whic latter at their other engs are riveted to the fixedplates p fixed to the channel-irons p.

Mounted in suitable bearings at each end of the boom G are drums R,round which runs the conveyer-belt J. For the purgose of drivin theconveyer-belt J a motor of any suita le construction inay be fixed tothe under side of the boom G, preferably in proximity to the rear endthereof or in any other suitable position, and motion be transmittedtherefrom to the pulley r on the spindle r of the drum R through themedium of a drivingbelt r from the pulle s on the motor-shaft. In orderto support t e conveyer-belt J as it travels from the receiving to thedeliver end of the boom G, idlers or rollers revo ubly su ported inidler-frames y", are ed at suitable distances apart on the top of thetwo top angle-irons h. (See Fig. 8.) For the purpose of preventing theconveyer-belt J saging as it returns to the receiving end of the boom Greturn-idlers 7'? (see Fig). 3) may be arranged inside the boom G and esupported therein by suitable means.

At the rear of the boom G and fixed to the carriage or wheeled frame Cis a structure consisting of the channel-irons T, which serves forcarrying a hopper T and drum T of the main feed-belt T main feed-belt 'Iat one end receives the material to be distributed and at the other enddelivers it into the hop er T. In the bottom of the hopper T is ed arotatable conical chute T, constructed to deliver the material onto theconveyer-belt J in a forward direction or in the direction of travel ofthe belt J.

It will be apparent that the girders or beams for the frame of thecarriage C and also for the structure supporting the semicircular railor track, the vehicle traversing said track, and also for the boom maybe of any other suitable section or sections, or wooden beams may beemployed in the construction of some of these parts.

In Figs. 1 and 2 of the drawings the boom G is shown in its centralposition and depositing the material at the to of the dump B. Whenthematerial being eposited reaches the level of the dump at this point,the position of the boom G is altered and the dumping continued The boomG is altered from timeto time as required between its two ex- (See Fig.1.) The treme positions at the ends of the semicircular track E or atright angles in two directions tothe position in WhlCh it. is shown inFigs. 1 and 2. The movement of the boom G is effected by rotating thedrum P of the winch by hand or power in the desired direction, whichcauses the vehicle M, supportin the boom G and conveyer-belt J to traveIround onthe semicircular track or rail 2. As the direction of the boom Gis altered the conical delivery-chute T is rotated to cause the materialto be delivered onto the center of the belt J and in the direction inwhich the belt is traveling. When the boom G is swung round, it movesround the pivot-pin 7c, and as it is being moved round it simultaneouslyoscillates in a direction at right angles on the other pivot-pin L andits point of sus ension inside the archedupper frame m of t e vehicle M.This prevents the inclining or tilting of the conveyer-belt Jtransversely, which would cause the material being conve ed to fall overthe edges of the belt J when t 'e latter is swung to either side of themain track A.

In Fig. 10 the boom G (and with it the conveyer-belt J) is shownin theposition it assumes when it is swung into a position at right angles tothat in which it is shown in Figs. 1 and 2. When the dump B has beenfilled up within the range of travel of the boom G, the wheeled frame orcarriage C is moved up the main track A until the end of the boom Gprojects over the edge of the dump 'B,. and the distribution of thematerial then continued. The distributer is moved up the dum from timeto time as required.
